Cheapest tactic. +- **`intro h1 h2`** — introduce hypotheses. +- **`constructor`** — decompose a goal that's a + `∧` / `∃` / similar. +- **`rcases`** — pattern-match on a hypothesis. + +`algebra-owner`'s round-22 win: replaced `nlinarith`-heavy proofs +with `abel`/`ring` closes, sorry count dropped from 7 to +5. + +## Term mode vs tactic mode + +- **Term mode** — write the proof as a lambda term. + `theorem foo : P := fun h => ...`.

A Mac + developer discovering a Linux install-script bug + belongs in CI, not in a ticket filed three weeks + later. "Works on my machine" is the bug class this + rule eliminates. + + **Implications:** + - The install script is idempotent.

Policy: + + - **Active** — the design is still landing; the doc + is current-state. Edit in place per §2 when the + decision evolves. + - **Landed** — the design shipped. The doc becomes + historical rationale (like an ADR). Move to + `docs/DECISIONS/YYYY-MM-DD-.md` on a + calendar date that matches the landing; keep in + place under `docs/research/` if it's still a + live reference surface (e.g., the gate inventory + that CI continues to audit against). + - **Obsolete** — the design was rejected or + superseded. Move to `docs/_retired/` with a + one-paragraph note explaining what replaced it, + OR delete (git history preserves the rationale). + `sweep-refs` is wearable for the reference sweep. + + **Quarterly review.** `maintainability-reviewer` or + `factory-audit` walks the `docs/research/` directory + every ~10 rounds and classifies each doc as active / + landed / obsolete. Orphan design docs (no references, + no ongoing relevance) are retirement candidates. + +27. **Abstraction layers — skills, roles, personas.** + + The factory has three layers of naming, ordered from + most-permanent to least: + + - **Skills** — capabilities the factory offers. + Slug-named (`harsh-critic`, `devops-engineer`, + `performance-engineer`). Live under `.claude/ + skills//SKILL.md`. Skills describe WHAT is + done and HOW; they are reassignable across the + persona population without revision. + - **Roles** — role assignments. Identical name to + the primary skill slug most of the time (role + `devops-engineer` invokes skill `devops-engineer`). + A role can wear more than one skill (e.g., the + `skill-expert` role wears `skill-tune-up` + + `skill-gap-finder`). Roles are the layer where + a persona gets assigned. + - **Personas** — named contributors (agents). Kenji, + Aarav, Dejan, Kira, Rune, etc. A persona is + assigned to one or more roles. Live on + `.claude/agents/.md` + `memory/persona/ + .md`. + + **The abstraction rule.** + + - **Skill files reference role names**, not persona + names. `pair with harsh-critic` is good; `pair with + Kira` leaks the persona layer through the + abstraction. + - **Role files reference skill names AND the assigned + persona**. That's the layer where the mapping + lives. `.claude/agents/devops-engineer.md` + legitimately names Dejan. + - **`docs/EXPERT-REGISTRY.md` is the mapping table.** + The one canonical place that ties role names to + persona names. Other docs reference roles, not + personas, for permanence. + - **Exceptions for meta-skills.** `factory-audit`, + `skill-gap-finder`, `skill-tune-up`, `skill- + improver`, `agent-experience-researcher` — these + meta-skills have personas / the registry IN + their domain, so discussing the mapping is + allowed. + + **Why.** A persona can be reassigned to a different + role, or a named contributor can leave the roster. + When that happens, skill files shouldn't need + rewriting. Abstraction-layer leaks produce O(N) + rewrites on every reassignment; respecting the layer + keeps the rewrite cost at the role/persona layer + only. + + **DRY corollary.** Skills that duplicate the same + "Coordination" boilerplate across ten files are a + smell.
